Embodiment Construction
[0036] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0037] The faulty application replica processing method provided by this application can be applied to such as figure 1 shown in the application environment. The application environment includes a master application copy 102 and at least one backup application copy 104 , the backup application copy 104 includes a backup application copy after fault repair, wherein the master application copy 102 communicates with the backup application copy 104 through the network. Wherein, the replica 102 and the backup application replica 104 may be the same application deployed on diff...

The invention relates to a fault application copy processing method and device, computer equipment and a storage medium. The method comprises the following steps: starting a standby application copy subjected to fault repair, and determining a main application copy which is normally operated at present in a cluster where the standby application copy is located; and determining a first message thatthe main application copy is currently performing service processing when the standby application copy after fault repair is started. Obtaining a second message with the receiving time after the first message, and searching a historical message with the receiving time before the first message; and according to the receiving time corresponding to the historical message, performing service processing on the historical message in sequence. And after the historical message processing is completed, performing service processing on the second message in sequence according to the receiving time of the second message, so that the local standby application copy is re-added into the cluster. By adopting the method, the time for rejoining the fault application copies into the cluster can be shortened, and the high availability of the distributed system is improved.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular to a method, device, computer equipment and storage medium for processing faulty application replicas. Background technique [0002] With the development of computer technology, a distributed system appears. A distributed system is a software system built on the network. The distributed system has a high degree of cohesion and transparency. In general, a software system with high availability requirements will deploy multiple application copies (application copies are deployed on different hosts for the same application) to form a cluster in order to improve the system's availability, acting as a whole to provide external services. When an application copy in the cluster fails, other application copies continue to provide external services to ensure high availability of the system. When the application replica fails, there are two commonly used methods to deal with ...
